Hypesia stone found in the Egyptian desert may be the first evidence of a rare type of supernova

Kameň Hypatia môže byť dôkazom vzácneho typu supernovy

Type Ia supernovae are relatively rare cosmic explosions and are one of the most energetic events in the universe. Chemical analysis of Hypesia rock found in the Egyptian desert may provide new information about this type of supernova, writes Johannesburg University Portal.

Behind the study are three scientists, John Kramers, Georgie Belianin, and Hartmut Winkler, who have since 2013 discovered a number of unusual chemical markers on a fragment of the hypothesized stone. Based on these signs, in their new research, they made a bloody rejection of various conditions that may lead to the formation of a stone. They have created a timeline that goes back to the origin of our solar system.

It is believed that the red branch is behind the formation of hyperemia stone. This is the final stage before a star similar to our Sun forms a white dwarf. This star was in the binary system, that is, in the system where another star is located. The resulting white dwarf began to absorb the mass of a related star, and at one point exploded to form a Type Ia supernova. After gas Supernovae It gradually cooled and began to stick to the surrounding dust. Over time, a solid body formed, from which the hypoxic stone eventually burst and ended up on the ground.

“Basically, we’ve caught a supernova,” he said. The gas atoms from the explosion were trapped in the surrounding dust, “Kramers explained.

Evidence of the most energetic events in the universe

By the time our solar system was created, gas trapped in dust particles had become a solid. Interestingly, the body from which the hypothesis stone originated was formed in the Oort cloud near the Solar System. It is not clear exactly when, but at some point the body began to jump to the ground. It enters our atmosphere and breaks down due to the temperature and pressure of the impact, which directly leads to the formation of rock.

The situation described above is still a theory, but if it is true, This is the first evidence of a supernova IA discovered by scientists on Earth. If scientists are to be able to compile a timeline about the origin of the hyperemia stone, they need to use several specialized techniques. In 2013, using argon isotopes, it was discovered that the stone did not come from Earth. In 2015, an analysis of rare gases revealed that the structure of the rock did not resemble any known type of meteorite or comet. Three years later, scientists discovered a mineral never before found in the Solar System.

In the new study, the researchers did not want to focus on all the anomalies that the stone represents. Instead, they decided to find out if there was any stable chemical formula in the sample. They were able to find a pattern of elements that are different from everything else in our solar system. The tracks led them out of our system, into the white dwarves. Scientists knew that the white dwarf could be in the binary system Absorb the substance Its cousin, becomes unstable and then explodes into a Type Ia supernova. This type of supernova can produce strong chemicals suitable for the structure of the hyperemia stone.
